"What’s funny, and I think helpful, is that we consume more Disney stuff than we create," Kristen said. "Bobby keeps buying 'Frozen' merchandise and filling our entire studio with all-things 'Frozen.'"

Creating songs for Disney isn't anything new for the couple, who also wrote pieces for the 2011 Disney animated feature, “Winnie the Pooh,” “Finding Nemo—The Musical” at Disney’s Animal Kingdom and "The Seas with Nemo and Friends" at Epcot.

The pair even featured their young daughters, Anna and Katie, in the film's songs.

The couple also worked with the president of Walt Disney Music, Chris Montan, while working on their songs for the movie.

"We called him ‘Gandalf’ because this was an epic journey. We really had to get that ring of Mordor and we had a very small window of time," Kristen said. "Neither of us had ever done this kind of thing before, so we would turn to Chris."
